• Design, deploy, and maintain Imubit’s cloud infrastructure to provide high uptime, scalability, and security.
• Leverage public cloud services and tools to improve the efficiency and reliability of our services and workflows.
• Architect and manage cross-cloud network infrastructure (e.g. subnets, routing tables, IPSec VPNs, Transit Gateways, firewall rules).
• Engage in and improve the whole lifecycle of services, from inception and design, through deployment, operation, and refinement.
• Participate in infrastructure on-call rotation and respond in a timely manner.
• Scale systems sustainably through mechanisms like automation, and evolve systems by pushing for changes that improve reliability and velocity.

• 5+ years owning and managing production cloud infrastructure, with a strong focus on AWS services (EKS, RDS, IAM, S3, VPC, Lambda, CloudWatch)
• Deep, hands-on expertise operating Kubernetes clusters in production, including k8s and GitOps tooling (e.g. ArgoCD, Helm, Kustomize, and Karpenter)
• Proven experience architecting, automating, and maintaining infrastructure using Terraform and modern IaC practices
• Strong experience with observability stacks (e.g. Grafana, Prometheus, Loki, New Relic, Splunk); able to define and instrument actionable SLOs and alerts
• Proficiency in Python, Go, or equivalent programming languages for automation and tooling; able to read, debug, and suggest improvements through code review
• Expertise in developing CI/CD pipelines and managing version control systems (e.g. Gitlab, Github) to support modern DevOps workflows
• Experience managing production databases (e.g. PostgreSQL, CloudNativePG), including configuration, monitoring, and performance optimization
• Demonstrated ownership of critical systems and a track record of improving uptime, scalability, and performance through automation and systematic problem-solving
• Experience applying security best practices and managing secrets using tools such as HashiCorp Vault and AWS Secrets Manager to ensure secure, compliant infrastructure
• Excellent communication and collaboration skills with the ability to mentor peers and influence architecture decisions

• B.Sc. / B.Eng. / B.Tech. in Computer Science or equivalent
• 8+ years of total industry experience, including at least 3 years at companies with fewer than 300 employees
